Hobbs State Park / Conservation Management Area, Northwest Arkansas

Camassia scilloides
Back in April of this year Brian and I spent a week in the Eureka Springs area of northwestern Arkansas. We're planning a relocation there the first half of next year some time. This is prime Ozarks territory and the countryside is verdant, lush and green.

I picked up a hiking book at the local megabookstore during our day trip to Fayetteville and thumbed through it for a day or so. There were a couple hikes that were close to Eureka Springs: Lake Leatherwood and Shaddox Hollow Loop in the Hobbs State Park / Conservation Management Area. I've already blogged about Lake Leatherwood.
Camassia scilloides

The drive from Eureka Springs over to Shaddox Hollow took me through rolling green hills dotted with houses, farms, and the occasional light industry. I see a flash of pale blue go by to my right, on the north side of the road. A few u-turns later on the sleepy road I find a safe place to pull over. I get out of the car and walk back a dozen yards or so to find a spectacular mass bloom of Camassia scilloides. This is only the second species of Camassia I've seen, but I really love them. The pale blue heads of flowers evoke blue fireworks going off over the grass. An added bonus - the hillside is in the shadow of the morning sun and dew droplets are everywhere.
Trillium viridescens
I was very pleasantly surprised to find a robust and healthy colony of Trillium viridescens in the ditch itself! They were a little wind and insect damaged but were otherwise in great shape, with almost all plants in bloom.

Once I enter Hobbs State Park, the farms and houses disappear and the forest comes almost up to the side of the road. Along the shoulder were miles of Viola pedata, one of the showiest Viola I've ever seen! Upon reaching Shaddox Hollow I check in on the clipboard at the trailhead and head out. I didn't stay long - the entire area had undergone a controlled burn 4 weeks earlier. Burns of this nature are an integral part of maintaining a healthy forest but you have to visit them the next season, not 4 weeks, to see what a positive effect they have. After about 20 minutes and realizing the burn covered the entire area I headed back to the car.

Viola pedata
Arisaema atrorubens
On the drive in, I'd noticed a few other trailheads so I stopped at one of them on the way back: Van Winkle Hollow. The main attraction here is a restored lumber mill and attendant examples of life in the area during the mid-19th century. More interesting to me was a short wildflower trail right off the parking area. The trail was a short loop around the creek in the hollow. I noticed a controlled burn had happened here, too, but stopped short about 15 yards from the water's edge. A full crop of wildflowers was in bloom!
 I was greeted by a bright yellow clump of Senecio aureus along the water's edge at the start of the trail. Drifts of Polemonium reptans and Collinsia verna were along both sides of the trail. Then I spot Arisaema atrorubens. It was stunning! A surprisingly large flower, almost 2 feet tall, it really lives up to the Jack-in-the-Pulpit common name. This was quickly followed by another spectacular find, the miniature crested iris, Iris cristata.

Collinsia verna
As I continued down the trail, there were Vitis vines here and there, surprisingly little Japanese honeysuckle, but it was present. The American Dogwood, Cornus florida, were almost finished blooming but every so often one would be in perfect condition. I started seeing large patches of Podophyllum peltatum along with Phlox divaricata.

Iris cristata
Taking a detour up to the edge of the floodplain and up the gently sloping hillside i find a huge colony of Adiantum pedatum. The newly emerging fronds were captivating. Other species I noticed were Ribes missouriense, Viola pubescens, Hydrophyllum virginianum, and lots of Delphinium. One of the last things on the trail was a large Platanus occidentalis with a hole in the base of the trunk. The tree was leaning a bit but otherwise seemed perfectly fine. Nature!

Here are some additional shots from the day:

Clarkia!

Late spring and early summer in California means Clarkia. These bright and lively members of the Onagraceae are a welcome sight as the green of spring turns into the golden summer in California. Here are some of the species I've photographed in California.

Clarkia concinna
Clarkia purpurea
Clarkia modesta
Clarkia rubicunda
Clarkia unguiculata
Clarkia purpurea ssp. quadrivulnera
Clarkia breweri
Clarkia gracilis
Clarkia epilobioides

Calochortus Parade, part 4

The fourth and final installment of Calochortus Parade features the Star Tulips. I've only encountered two species of Star Tulips in the wild - C. umbellatus at Ring Mountain and C. minimus from Yosemite National Park. Both species are incredibly enchanting.

C. umbellatus is a lovely pale/blush pink flower that blooms early - with the early spring annuals, starting in mid-March, staying in bloom for about 4 to 6 weeks at Ring Mountain. The flowers are small, about 2 inches across, nestled in the grass in many places, turning them into little hidden jewels.

C. minimus is an even smaller pure white flower, approximately one inch in diameter. It was easy to step on them before I realized what was underfoot! It blooms in the Yosemite 'spring' - a time that is always dependent upon the snowmelt. I saw it in early to mid-June but I imagine it could be found later or earlier depending upon how much snow has to melt from the higher meadows.

Calochortus Parade, part 3

Serpentine is the 'common name' for serpentinite, a shiny, smooth, mostly green metamorphic rock that is present in fairly large quantities throughout California. It is produced at the margins of the continental crust, particularly on ocean floors, through a complex process involving seawater reacting with mafic and ultramafic rocks to form serpentinite. It is the state rock of California.

Soils derived from serpentine rock are high in several metals, particularly magnesium, and low in most plant nutrients. This prevents most plants from growing in serpentine soils, except those that have evolved a special ability to tolerate these unusual conditions. These plants are called serpentine endemics. There are also plants that are tolerant of serpentine but that can also grow in regular soils.

Calochortus are one of the groups of plants with a high number of serpentine endemic and tolerant species. Perhaps the most famous is Calochortus tiburonensis, a species only discovered in the early 1970s growing in serpentine outcrops on Ring Mountain, in southern Marin county, at the base of the Tiburon peninsula.

The third installment of the Calochortus Parade will focus on the Cat's Ears floral style, of which C. tiburonensis is a member.

Calochortus Parade, part 1

California's state flower is Eschscholzia californica, the California Poppy. Some accounts indicate it won out over competitors Romneya coulteri and flowers in the genus Calochortus, the Mariposa Lilies.

People tend root for the underdog and as such I personally wish a species of Calochortus, or perhaps the entire genus, were the state flower. They come in a wide variety of shapes, forms, and colors, and have a long bloom period, starting in late March and in some places ending up in August!

So to honor my underdog, here is the first installament of the Calochortus Parade: the Mariposa Lilies!

Species, from top: C. superbus, C. leichtlinii, C. venustus, C. luteus, C. argillosus, C. vestae
